, G. U7 {4 }$ }( R+ ^2 |As the garage door opener is old, I assume your door is old as well. So first thing to do, checkit manually if there is a mechanical problem. Most time it is a broken Spring or mechancal jam somewhere.& Y# l1 E( t, j, M

To check it manually, it needs to seperate the door opener chain and garage door. Usually it has a pullcord with a latch. Pull the cord down, it will seperate the door opener. Make sure there is no body under the garage as the door may smash to the ground to hurt someoneles if you have a borken spring.; J9 E- N. s. e" ~& Q( O

Then, use you hand to open and close the door by hands, it shall move smoothly, does not need too much force to be up or down. If it could not open or close, you may need to check Coil Spring above the garage door. If double door, you have 2 springs. Check springs at both side to see if it broke. The spring tension is to carry the weight of the door. and then check if there is any jam somewhere. Loosing screws and bend track... lube it tracks and joints if possible.

Then you may check the motor when the door is detached to see if the motor is still runnning.

If all above things are all good, you may put opener back, and try to adjust the "tesnison"

$ s2 @5 Q( N: s, R O u. xBut by all means, I would like to recommend you to have a garage door specialist to come over to check out, not an electrician like me. It is very dangerous as the spring tension can easily damage your whole door and hurt someonelse.

Furthermore, the garage door specialist charges less than a normal electrican, but he has way more experience to do the job safely. |
